Dear Ryo and Russ,
 
Thank you for your reply. What other info would be helpful to diagnose 
the problem?
Here the ncdump output, I could also upload the file somewhere
 
dimensions:
time_counter = UNLIMITED ; // (1 currently)
bnds = 2 ;
lon = 180 ;
lat = 90 ;
lat_2 = 90 ;
num_ani = 10 ;
veget = 13 ;

float time_counter(time_counter) ;
time_counter:standard_name = "time" ;
time_counter:long_name = "Time axis" ;

time_counter:units = "seconds since 1901-01-01 00:00:00" ;
time_counter:calendar = "365_day" ;
time_counter:axis = "T" ;

Thanks!
